Fuss & O’Neill traces its roots to 1924 as a local survey practice founded by Hayden Griswold, Sr. Growth in the 1960s and 1970s added expertise in
land development, transportation, structures, water and sewer systems, and water resources. In 1971 the firm became Griswold & Fuss, and then
Fuss & O’Neill in the late 1970s. The early 1980s saw expansion into emerging fields of environmental compliance and permitting, and site assessment and remediation. Today the company continues to expand its expertise as engineering innovation and technological advances unfold.
Fuss & O’Neill chooses to partner with like-minded firms who share a sense of the greater purpose of the work that we do for our clients and in our communities. We work on engagements that require high-quality consulting engineering expertise, whether it’s a discrete service or a more involved relationship. Our engineers, scientists and planners bring decades of experience delivering integrated services across our multiple disciplines, which allows us to provide a level of insight and best practices that adds to the overall quality of the project.
Our Limited Liability Companies bring their own expression of focused diversity to our organization, adding another layer of collaboration to bring the best possible results for our clients. As a company that offers a diverse group of services over multiple disciplines, we bring a considerable amount of project- and industry-specific knowledge that allows us to be efficient, creative and cost-effective. Fuss & O’Neill has both the technical expertise that highly technical projects require, and the hands-on knowledge that it takes to successfully manage every detail.
Fuss & O’Neill has ten regional offices that support our three LLCs and more than 320 employees who maintain licenses and certifications across a breadth of technical disciplines. Many of our staff across these offices are actively involved in leadership roles within industry professional organizations.
